well as otherwise finishing them inorder to 1 give them the ornamental appearance desired.

The parts usually burnished are known technically as the heel, the top piece, the heel breast, the shank, the fore part, and

I further desire to provide a machine of the character noted with means for automatically feeding wax to the burnishmg tool, and so design this latter that it is capable of operating to finish the rand,'as well as to indent the portion adjacent said rand.

Another object of the invention 1s to providea polishing or burnishing tool particularly adapted to rapidly produce a high finish on the heel or other part of a shoe and that without possibility of injury to the parts acted on..

The invention also contemplates a .novel arrangement and construction of rand and indenting wheels, preferably though not necessarily, burnishing tool in acting upon a heel to be burnished.

These objects and other advantageous ends I secure as hereinafter'set forth, reference being had to the'accompanying drawings,.in which v Figure 1, is a plan of a machine constructed according to my invention; Fig. 2, is an end elevation of the machine shown in Fig. 1; Figs. 3 and 4 are vertical sections at right angles to each other showing the construction of the burnishing tool; F igs.

In the above drawings, 1 represents the supporting frame of the machine on which are mounted bearings 2 carrying a plurality of concentric shafts 3 and 4, and parallel with these shafts is a second or counter shaft 5 extending through the casing 6 of an exhauster driven through a belt 7 transmitting power between a pulley 8 on the shaft 3 and a second pulley 9 on said shaft. 5. Said shaft. 3 is provided with fast andloose pulleys 10. and 11, of which the first may be driven from any suitable source of power and also has fixed to it a series of brushes 12, 13, and 14 provided with hoods 15 and 16 connected to the inlet 17 of the exhauster 6, preferably in the manner disclosed and claimed in my pending application forPatent No. 544,604 filed March 1, 1910.

The inner shaft l-has fixed to one end a pulley 18 connected through a twisted belt 19 with a pulley 20' on the shaft 5, so that this inner shaft, under operating conditions,

is turned in a direction opposite to that of the'shaft 3.

One of the vital features of my present invention consists in a burnishing wheel 21 -which is mounted on the shaft-s 3 and 1 on" the end opposite that having the pulley 18-. This burnishing wheel, shown best in Figs. 3 anda, cdnsists of two flanges 22 and 23, preferably though not necessarily formed integral with the shaft '3 and having extended between them, two or more series of bolts or rods 24 preferably staggered and so arranged that the bolts of each series are at the same distance from the center of the shaft. On each of said bolts is mounted a series of burnishing elements 25, which in the case shown in Figs. 3'and 4, are spaced at definite distances apart by sleeves 26 on the bolts 24. i

It will be understood that the burnishing elements maybe made in any of a number of different forms, and while those shown;

shown in Fig. 7 consist of flat blades 25 of substantially uniform thickness but of increasing width from one end to the other. The elements shown in Fig. 15 consist of a piece of wire 25 having an eye 25 at one endand a ball 25 at the other. In any case the various burnishing elements are stag- .gered both transversely of the burnishing tool as well as longitudinally, so that they engage any surface which may be presented to them at a number of different points and do not produce a wavy appearance, as would be the case if the various sets struck in the samelines.

It will be understood that the lengths of the various burnishing members may be varied in any desired manner to produce diflerent contours of burnishing tools adapted to operate on the different parts of a shoe, and in Figs. 9 to 14 inclusive I have illustrated this feature, as well as some of the various forms in which the tool may be made and used. In order to secure the tion of power to the fast pulley 10 turns the burnishing tool 21 through the shaft 3,

and if any of, the various portions of the shoe be presented to said tool, the burnishing elements so act on its surfaces as to give it a perfectly smooth surface and a high permanent polish; it being understood that the coloring and other material may be applied to the shoe operated on previous to its presentation to the burnishing tool, as will be understood by those skilled in the art.

In order to secure the best effects, it is advisable that the tool be heated while it is in use and for this purpose I make the shaft 4 hollow and connect it through a swivel joint 30 with a source of fuel supply. The

opposite end of said shaft within theburnishing tool 21 is provided with radial openings 31 and the-adjacent end of the shaft 3 has corresponding openings 32 through which the fuel may escape into the body of the tool so as to be capable of heating' the same under conditions of use.

For the purpose of supplying air to the gas in the shaft 4 so that the device may act as a Bunsen burner, I provide the pulley wheel 18 with a series of goose neck pipes 33 which as shown in Figs. 5 and 6, communicate through suitable openings with the interior of the shaft 4. With this arrangement the turning of the pulley wheel causes air to be drawn or forced into the shaft through the goose necks 33, which are preferably provided with adjusting screws 34 whereby the flow of air through them may be varied asdesired.

When the heel of a'shoe is applied to the burnishing tool of the construction shown in Fig. 4, the rand wheel 27 engages and finishes the rand thereof, while the indenting wheel 28 acts on the edge of said heel immediately adjacent the rand to form the ornamental indentations desired.

From the arrangement of parts described and shown it is obvious that the rand wheel 27 is turned in the direction opposite that in which the various burnishing elements are turned, while the indenting wheel is independent of both of these parts, so that as the shoe is swung back and forth in the act of burnishing the heel, the teeth of the indenting wheel repeatedly engage the same portions of said heel and form indentations of the desired depth.

During the finishing operation it is necessary that wax be supplied to the burnishing tool and for the purpose of accomplishing this end, I mount on a suitable portion of the frame 1, a bracket 34 having a guideway 35 for the stick of wax X whereby 1ts end immediately adjacent the burnishing wheel is steadied and properly directed.

From Fig. 1, it will be seen that the bracket 34 projects rearwardly from said wheel and guideway and has at about its middle point, two forked or yoke shaped guides 36, spaced apart and deslgned to receive a screw 37 for forcing the stick of wax X toward the burnishing wheel. This screw has mounted on it between the two abutments 36, a worm wheel 38, with which engages a worm 39 carried on a spindle 40 supported in suitable bearings 41. Fixed to this latter spindle is a ratchet wheel 42 having a pawl 43 carried on a swinging arm and connected through a link 44 with a lever 45 fulcrumed on a suitable portion of the supporting frame. The shaft 3 has fixed to it a cam 46 and a spring 47 holds the lever 45 in engagement with said cam so that revolution of the shaft causes an oscillation of the lever. The link 44 may be adjusted as to the length of its stroke, since, as shown in Fig. 2, the lever 45 has an elongated slot 48, in any portion of which the end of said link may be fixed. With this arrangement of parts, the revolution of the a shaft 3 causes an intermittent turning of the ratchet 42 through the agency of the link 44 and pawl 43 so that there is a corresponding movement of'the worm 39 and of the worm wheel 38. Since the screw 37 is threaded through the hub of said worm wheel, it is also turned at a relatively slow If desired, or found advisable, the burnishing tool may be still further heated under operating conditions byany suitable ,means and there is also provided a supporting bracket 50 adjacent the front of the tool for supporting the shoe while it is being operated on. Said bracket is so mounted as to be adjustable to suit it to properly support shoes of different styles; being slidably mounted on a block 51 and if desired otherwise adjustably supported to attain the desired object.

While the supporting bracket itself may be of any desired form, it is preferably made of a stiff or rigid rod whose body is curved parallel with the surface of the burnishing tool.

It will be noted that the various burnishing elements under operating conditions are maintained in their radial positions under the action of centrifugal forceand act on the body to be polished by delivering to the same a series of light, glancing blows.

Since each one of the tools has a relatively large number of burnishing elements and since under operating conditions the shaft carrying them is turned at 'a high Q 5 speed, their extremities together form a polishing or burnishing surface.
